Open Vehicles has introduced OVMS, an open source system that allows EV owners to remotely monitor, diagnose, and control their vehicles. The platform offers live data, alerts, and control features through a web app and mobile apps, with extensive integration capabilities.
Open Vehicles has announced the release of OVMS, an open source platform designed for remote monitoring, diagnosis, and control of electric vehicles, expanding user customization and integration options.
OVMS provides real-time monitoring of vehicle metrics such as state of charge, temperatures, tyre pressures, and fault conditions. It offers push notifications for critical events like charge aborts, battery cell failures, or potential theft, directly to users’ smartphones. The platform supports control over charging, climate, engine tuning, and scripting interfaces for external systems, depending on vehicle integration.
The system features a web app interface, native Android and iOS apps, and integration with home automation systems via MQTT. It also supports data logging to SD cards and remote servers. OVMS connects through three CAN buses, offers a configurable OBD2 translator, CAN tools, and a reverse engineering toolkit. It provides SSH access, WebSocket streaming, and CAN frame injection over TCP, aiming for extensive control and data access for EV owners and developers.
Why It Matters
This development matters because it empowers EV owners and developers with open source tools for detailed vehicle management, diagnostics, and customization. It enhances vehicle security, maintenance, and operational control, potentially reducing reliance on manufacturer-specific systems and fostering innovation in EV technology.
